Technical Specifications

Core Structure

Bit Body: C31HD kennametal auger teeth with high quality alloy steel, with special heat treatment to reduce wear and tear.

Teeth type: conical cutter bits (tungsten carbide content ≥85%, cobalt content ≥13%).

Tooth Pattern: Optimized, asymmetric pattern that provides increased resistance to impacts and reduced balling up.

Key Performance Features

High Penetration Ratio: C31HD kennametal auger teeth concentrate and point-load stress (>200kN/tooth) to break hard and abrasive formations.

Impact & Wear Resistance : Hardness of Tooth Surface HRC 48 ≥; Toughness of Fracture > 15Mpa m 1/2.

Thermal Stability: Working temperature range: -50 deg C to +350 deg C (with coolant).

Hydraulic Design

Flow Distribution: The deducted fluid path for effective removal of cuttings and cooling of the bit.

Connection & Dimensional Specs

Thread Type: API REG or 4½" FH (Can be customized as API 7-1).

Gauge Protection: Tungsten carbide inserts on gauge surface for gauge protection.

Bit Diameter: 8½" ~ 26" (C31HD kennametal carbide teeth is commonly used for 12¼").

Geological Applicability

Target Formations:

Ideal: Quartzite, granite, chert, etc. and other high abrasive strata (UCS: 150-350 MPa).

Compatible: Mixed (shale, sandstone) formations with interbedded shale.

RPM Range 60–180 RPM (maximum WOB: 20–50 tons).

Anti Sided Lego-Design: Tapered clean side prevents bit from dragging and improve clean hole.

Welding Process of Teeth: Combined vacuum brazing and HIP (hot isostatic pressing) process for minimizing micro-cracks.
